l a number of small perforations e through which the air at various points, both above and below the opening a, may enter the iire cup from the channel. Becauseof thedabsence of openings through the plate or partition E opposite the opening a, it will be evident that air passing with force through To @ZZ whom, t may concern:

Be it known that I, FRANCIS DANZEN- BAKER, of IVashington, in the District of Columbia, have invented a certain new and useful Improvement in Bee-Smokers; and I do hereby declare that the following is a full, clear and exact description thereof, reference being had to the accompanying drawings, in such opening a and striking the imperforate whichportion of the plate or partition, will be de- Figure l is a perspective view of a beeiiected up and down the channel.' I have no smo ier constructed according to my invention Fig. 2 is a vertical section of the Same 5 Fig. 3 is a horizontal section through the fire cup on the line 3-3 of Fig.2, and Fig. 4 is a detail view of a fragment of the fire-cup lining.

The object of my invention is to improve the construction of bee-smokers, whereby they will be simplified, their cost of manufacture cheapened, their efficiency increased, and they bettered in other respects, and to these ends my invention-consists in the smoker constructed substantially as hereinafter specified and claimed.

My smoker is of the type which comprises a cylindrical stove or fire cup and a bellows attached to the fire cup, at the side thereof, by which air is supplied, under pressure, both to maintain combustion in the fire cup and to cause the expulsion of smoke therefrom.

The stove or fire cup, A, consists of a simple or plain cylinder whose bottom is permanently closed and whose top has a removable lid or cover B, the fuelY being accordingly placed in the fire cup through the top thereof. The lid or cover may be a simple cap adapted to be slipped on and off the top of the fire cup, but I preferably hinge or pivot it, employing for this purpose a strip of sheet metal C that is riveted to the lid or cover and at one end is pivoted to the vertical extension d of the upper one of the brackets D that unite the iire cup and bellows.

Air'enters the fire cup through a hole a at or near its vertical center, and it passes up and down therein through a vertical channel formed by a plate or partition E that extends from a point close to the bottom of the fire cup to a point nearly to the top thereof, the channel being closed at the top but open at the bottom, so that air may emerge therefrom at the bottom of the re cup to support combustion of material down to the very bottom of the iire cup, and thus assure the burning of all the material in the cup. At points both above and below, but not in line with the opening a, the plate or partition E has grate at the bottom of the fire cup, but the burning fuel rests directly upon the bottom of the cup, which consists of a piece of sheet metal and a sheet of asbestos paper, or the like, covering it to protect'flit from thehcat. The bottom, it is to be observed, is supported a short distance above the bottom edge of the cup, so that when the latter stands upon a surface its bottom will not burn the same.

The plate or partition E has, at opposite edges, flanges e that lie against the inner surface of the fire cup, and such flanges are attached to the fire cup, the same rivets being utilized to fasten themf to the fire cup that unite the brackets D to the latter. The plate or partition is made of heavy sheet metal that it may withstand the heat.

To keep the iire cup cool, and thus increase its durability, as well as the comfortof handling the smoker, I preferably provide it with a lining of asbestos or other non-conductor of heat, which extends from the bottom to, or nearly to, the top of the cup. A very convenient way of applying this lining is to apply it in the form of a sheet a2 to a circular or partly cylindrical shell a3 of sheet metal,

edges of thesheet of asbestos, theA whole thing snugly fitting the fire -cup and extending around in the same from one flange e of the plate or partition E to the other flange thereof, as clearly shown in Fig. 3 of the drawings. Each of said flanges'iat its free edge is bent away from the 'wall yof the fire cup to receive the edge of the lining. This lining device is not attached to the fire cup but is readily removable therefrom, so that it may be removed and renewed very readily when necessary.

The smoke exit is at the top, or near the top, of the iire cup, and consists preferably of a simple hole a through the fire cup, without any nozzle in the form of a snout-like proj ection. The employment of a nozzle is objectionable, because it readily chokes up with soot and requires to be frequently cleaned whose edges are crimped or bent over the IOO IIC

out, so that, by the elimination of the nozzle at its opposite sides. Such extension, be-

sides serving as a smoke deflector, is also usel ful in opening the lid or cover, as it may readily be knocked or bumped against any suitable object for this purpose. Preferably the edges of the exit or opening a are turned outward a short distance, but neither this formation nor the employment of the deilector above the opening constitutes a nozzlel for there is nothing of this nature employed, and there can be no collection or accumulation of soot in the structure I employ. The rim or iiange of the lid or cover may be so short that its lower edge comes merely to the level of the top of the opening a, or it can be made of such length as to cause it to extend entirely over the opening a', in which event it would be provided with an opening to register with the opening a My bellows, as usual, consists of two boards F, connected together by a strip of leather G, one of the boards being movable toward and from the other to expel from and draw into the bellows, alternately, the air, a coil spring H being interposed between the two boards to move the movable one away from the other, but, of course, any other type of spring may be employed if preferred. Where I employ the coil spring, I secure its ends to the respective boards, which may be done by forming a point 7L on each end to enter the wood. The spring will thus be securely held in place against lateral movement, so that its power will always be exerted to the best advantage and the likelihood of its slipping sidewise and catching into the leather obviated, and it can be kept free from slack and under such tension as to utilize its energy to the best possible advantage. The air hole f in the stationary board of the' bellows is directly opposite the air inlet a in the fire cup, and I employ no valve for such hole. It is to be remarked that back draft from the fire cup into the bellows is prevented by having the portion of the plate or partition E opposite the fire cup air-opening (L imperforate. Preferably, I employ no thimble or sleeve between the bellows air hole and the inlet hole of the fire cup as, without the employment of such sleeve or thimble, an ample volume of air enters the fire cup, and there is an advantage in having some not enter it, but to strike and move along the sides of the re cup, in that the latter is thereby cooled on the side that is next the hands in grasping the bellows; but, if preferred, such a sleeve or thimble may be employed, and one is indicated in dotted lines in Fig. 2 of the drawings.

I round or curve the corners of the bellows boards, as shown in the drawings, to avoid any sharp or angular bends of the leather that would cut or otherwise damage it, and, at the same time, I secure a more pleasing appearance of the bellows.

It will be seen that my side and top burner, the air to support combustion passing into the channel formed by the side of the lire cup and the plate or partition E at its vertical center, and thence passp ing upward and downward and coming in contact with the burning -fuel all along the side thereof, as well as entering it at the bottom of the fire cup, and thence passing upward through it to the top.

It will be seen that my smoker is extremely simple `in construction; the iire cup has great i fuel capacity; the smoker operates most efficiently, and it is convenient and comforti able to handle.

'While I prefer struction which smoker is a direct the various details of con- I have illustrated and described, it is to be understood that the scope of the invention is not limited thereto, as

changes can be made which will involve no departure from the scope of my invention. Among other changes that may be made, I mention the employment of a differently constructed non-conducting lining for the fire eup, it being possible to use in place of that I have shown ribbed or corrugated paper of non-conducting material.

I do not claim herein the features of my bee-smoker wherein the smoke outlet has no snout; the strip to which the lire-cup lid or cover is attached, which projects over the smoke outlet; and the pivoting of the lid or cover to the bracket that connects the firecup and bellows, as claims thereto are in application No. 236,319, filed by me December io, 1904.. a

Having thus described my invention, what I claim is l. A bee-smoker comprising a fire cup having a channel, one side of which is formed by a perforated plate extending vertically through the cup, and having an air inlet that opens into said channel at the vertical center of the channel and means for forcing air into and through the smoker. p

2. A bee-smoker', comprising afire cup having a channel, one side of which is formed by a perforated, plate extending vertically through the cup and having an air inlet that opens into said channel at the vertical center y of the channel, and an air forcing device having an air outlet opposite said air inlet.
